I just got 2 Transcend 8GB Class6 cards in today from newegg.com. And when I try to load Ultimate Mortal Kombat. It says loading and then freezes up no soft key menu... nothing will show up just a black screen I then have to turn my DS off. I formatted the card 2 times with Panasonic SD Format. And still nothing.. If I take everything off the card and just put that game on it works.. I moved from a ScanDisk 8GB class2 card to the new one thats when I noticed the problem. Please help me in anyway you can. All my other games work fine.. I have also made a clean dump from the orginal card without trimming.. And still nothing. I am thinking this is a bug and needs to be checked out.
